Former 100m WR holder Asafa Powell ran the 400 last weekend, guess his time

The results does not mean as much as people think, when a pure short sprinter runs a 400m, you never know the amount of effort. Almost any sub-10 100m sprinter with a max effort can run a 47x 400m. The reason why I say 47x is becasue it is the pace they are familiar with. It is the pace they run their 200m-300m intervals in. A 100m sprinter is by default trained to run a 47x 400m with relative comfort. But, since they don't actually train to run the 400m and they know it is going to hurt, it is hard to get some of them to put out a max effort. Part of being a long sprinter is accepting and being able to power through the feeling of lactic burn. Lactic burn is a feeling a short sprinter only wants to feel for a couple seconds. Sort of like why a miler does not want to run a 10K, a miler is only trained to feel tired for about 2 minutes. Long story short, if Powell is in shape, he could almost certainly run a 47x 400 if he really wanted to.
